You shouldn't be a prisoner of your own ideas.
Most ideas that are successful are ludicrously simple
The thinking of John Cage derived from Duchamp and Dada. I was not interested in that.
Artists are mystics rather than rationalists. They leap to conclusions that logic cannot reach.
Buying books was a way anyone could acquire a work of art for very little.
Also, since art is a vehicle for the transmission of ideas through form, the reproduction of the form only reinforces the concept. It is the idea that is being reproduced. Anyone who understands the work of art owns it. We all own the Mona Lisa.
